A disappointment is what happens when things don't go your way. That sad, frustrated feeling of loss that follows? It's also called disappointment.

The noun disappointment comes from the Middle French word disappointer, meaning “undo the appointment,” or “remove from office.” It is true that a friend canceling your plans or losing your job is a disappointment, but today disappointment can describe anything that crushes your hopes, ruins your day, or otherwise lets you down.
